(1) From the fresh latex of Euphorbia cooperi N E Br was isolated by partition and chromatographic methods, a diterpene ester 12-deoxyphorbol-16-isobutyrate-13-tigliate.

(3) The anatomy of four skulls of the early Eocene omomyid Shoshonius cooperi--the first cranial material recovered for this genus--strongly suggests that Shoshonius shares a more recent common ancestry with Tarsius than do either anthropoids or other Eocene omomyids for which cranial anatomy is known.
(4) The effects of parasitism by leeches Theromyzon cooperi and Placobdella garoui on the redbilled teal Anas erythrorhyncha were investigated.
